DISPLAY DEVICE Filed April 21, 1930 2 Sheets-Sheet 2 Patented Nov. 17, 1931 ALBERT V. POLAK, F ATLANTA, GEORGIA nrsrnav nnvron Application filed. April 21, 1930. Serial No. 446,102.

This invention relates to a device adapted to be actuated by the vibration of a moving Vehicle, and to be hung or supported in or on such vehicle for display purposes, either for advertisement or amusement. The device is preferably constructed to simulate a human being, especially in the action of arms and legs, and the arrangement of parts is such that the movement of the vehicle to which the device is attached will cause action of the various extremities to occur in a human-like manner.

In the drawings,

Figure 1 is a representation of a football player in the act of kicking a football, showing the relative positions of the extremitie during actuation,

Figure 2 is a rear view of the device of Figure 1, showing the coordination of the arm and two legs,

Figure 3 is a View similar to Figure 2, showing the kicking leg at an uppermost position,

Figure 4 is a view in end elevation showing the. interrelated parts and the weighted foot,

Figure 5 is a representation of football player in the act of running with the ball,

Figure 6 is a rear view of the player of Figure 5, showing the coordinating mechanism of arm and legs,

Figures 7 and 8 are views similar to Figure 6 showing other positions of the same,

Figure 9 is a view in perspective of the mechanical features shown in Figure 6.

Referring specifically to Figure 5, which shows my preferred embodiment, the plate 1 is adapted to be attached to the rear window of an automobile and has a depending portion 2 which has secured to it by glue or other means the players head and body 3. Suitably pivoted to the body 3 by means of pin 4 is the movable outstretched arm 5, and likewise, suitably pivoted to the body by means of pin 6 is the movable pendant member 7 representing'legs 8 and 9. It is to be noted that in the form of the device shown in Figure 5, the legs 8 and 9 are rigidly secured together and relatively immovable with each other. The leg 8 is bent at the knee and carries the weight 10 (Figure 6). The movable arm 5 has secured thereto a cam making the entire arm function as a bellcrank lever. The cam 11 rides on the side edge e f-the frustoronical' end 12 of the pivoted member 7. When the automobile is set in motion, the weighted foot oscillates about the pivot 6, by reason of the gravitational attraction of the'weightand the sides sway of the car. The oscillatory motion oi the member 7, by reason of the cam 11, causes the arm 5 to move thru an arc the radius of which extends from pin 4 to the finger tips. The impression conveyed to the onlooker is that a football player-is engaged in broken- .65 field running, carrying the ball Victoriously for the college whose name is emblazoned on the plate 1.

Referring now to the embodiment shown in Figure 1, it will be noted that the plate 13 carries a head and body portion 14, to which is pivoted the arm 16 by means of pin 1'? and legs 18 and 19 by means of pin 20.

Further details are shown in Figure 2 and it is to be noted that leg 19 is weighted at 21 and also has secured thereto the member 22 upon which the cammed edge 23 of the leg 18 rides. The legs 18 and 19 are independent ly movable about their common pivot pin 20 and coact in their movement by virtue of member 22 and cammed edge 23. Upon the leg 18 there is secured by suitable cam braces 25 the strut 24-, in a manner permitting the arm 16 to extend between the strut and the leg 18, so that movement of the weighted 35 leg 19 is transmitted to leg 18, which in turn transmits motion to the arm 16 about the pivot 17 The impression conveyedto the observer is that of a football player punting the ball (Figure From the above description of the figures,

it will be seen that I have devised a novel mechanical arrangement which is pleasing to the eye and is adapted to be operated with ease and facility by vibratory motion. The various parts may be made of cardboard, wood, aluminum or other material as desired. If metal is used, it may be stamped, wrought or cast into the proper shape for the parts to be assembled. While I prefer the color scheme to be in accordance with the college colors in the locality Where the device is to be sold, it is obvious that any desirable ornamentation may be used.

IVithin the scope and spirit of my invention, I propose to claim all novel features broadly except as to the limitations imposed by the prior art.

Claims:

1. In a display device, the combination of a. body member simulating a human figure and having arms and legs, one of said arm members and one of said leg members being independently pivoted to said body member and free to oscillate thereon and one of said pivoted members being Weighted, and means on said Weighted member directly engaging the other pivoted member for transmitting motion to the latter member When said Weighted member is oscillated.

2. In a display device combination, a supporting plate comprising a body member simulating a human figure having arms and legs, one of said arm members and one of said leg members being independently pivoted to the body member and free to oscillate thereon, a weight carried by one of said pivoted members and means including a projection on the Weighted member and directly engaging the other pivoted member to cause movement of the latter member When oscillatory movement of the Weighted member takes place.

In testimony whereof I have hereunto set my hand.

ALBERT V. POLAK.
